Pat Gelsinger bets on light-based chips to revive Moore's law

Key Takeaways

• Gelsinger joined Playground Capital as general partner to fund semiconductor startups pushing past current lithography limits
• His first major bet is xLight, which aims to break past the 13.5-nanometer light wavelength used in today's chip manufacturing
• The semiconductor industry now expects to hit $1 trillion in 2026, pulled forward from 2030 projections due to AI demand

Pat Gelsinger left Intel in late 2024 and spent four months meeting with everyone from politicians to private equity firms. He landed at Playground Capital, a deep tech VC fund, with a specific mission: back the semiconductor startups that can restart Moore's law. His first major bet is xLight, a company developing lithography techniques that could push chip manufacturing past its current physical limits.

Why Gelsinger chose venture over private equity

After leaving Intel, Gelsinger considered government roles, university positions, and more CEO jobs. None stuck. His wife told him he wasn't done yet. The deciding factor came down to what he wanted his days to look like.

"Private equity writes bigger checks, but it's not as focused on the tech," Gelsinger told WIRED in early July at the RAISE Summit in Paris. "At this phase of my career, do I want to write big checks and worry about financial returns, or do I want to do cool tech? We're at the edge of science, proving things out."

He ruled out public company leadership entirely. No more quarterly earnings calls. The deductive process led him to Playground Capital, which specializes in deep tech bets built on new science rather than software plays.

The lithography problem holding back chip performance

Gordon Moore predicted in 1965 that transistor density would double roughly every two years. That held for decades. It's now hitting a wall. The leading lithography technology, developed by ASML in the Netherlands, uses 13.5-nanometer wavelength light to etch chip features. Shrinking transistors further has become prohibitively difficult and expensive.

Gelsinger sees light itself as the breakthrough point. "If we solve light, that is the hardest problem," he said. "Can I move past 13.5-nanometer light? That's the next breakthrough."

xLight, the portfolio company where Gelsinger took a board seat, is developing novel lithography techniques to do exactly that. The startup recently received investment from the US government alongside Playground's backing. Gelsinger repeatedly invoked the phrase "God said, 'Let there be light!'" when discussing the company's potential.

AI has pulled the semiconductor industry's $1 trillion milestone forward

The timing works in Gelsinger's favor. In 2024, the semiconductor industry projected it would hit $1 trillion in annual revenue by 2030. That target has accelerated dramatically. According to Gelsinger, the industry will reach $1 trillion next year, in 2026.

AI is the catalyst. The compute demands of training and running large models have created unprecedented demand for advanced chips. This shift has also redirected venture capital attention from software toward hardware and deep tech.

"The door has blown wide open," Gelsinger said. "I don't need my companies to win the market to get extraordinary returns. I just need them to win a decent percentage. That's what AI has done to deep tech venture."

How Playground vets deep tech founders

Evaluating startups built on unproven physics requires a different playbook than software due diligence. Gelsinger described Playground's investment team as deeply technical: engineers, PhDs, and professors. The firm runs what he called a "rigorous tech diligence process" with extensive interviews and background checks.

The key question: can founders articulate the hard problem in depth? "We're looking to fund the best team, not a team, on a given topic," Gelsinger said.

He acknowledged the inherent uncertainty in backing science that hasn't been fully proven. But he noted that deep tech ideas rarely emerge in isolation. "Generally, when you see deep tech things emerge, there's usually two or three companies gravitating to that idea. Very rarely do you find the dodo bird. Then you're asking, 'Am I picking the best one?'"

Most VCs have forgotten how to do deep tech

Gelsinger sees an opportunity gap. Many venture firms spent the past decade focused on software, SaaS, and consumer apps. The AI boom has them pivoting back to hardware and physical technology, but their muscle memory is weak.

"The good news is that a lot of venture firms are swinging in that direction," he said. "The bad news is that, for the most part, they've forgotten how to do deep tech, how to pick the winners and losers."

Few people have Gelsinger's background for this work. He spent his entire career at Intel before becoming CEO, starting as a quality assurance technician in 1979. He was the company's first CTO. That history gives him pattern recognition that software-focused VCs can't replicate quickly.

What this means for AI infrastructure

If xLight and similar startups succeed, the implications extend beyond chip manufacturing. More powerful processors at sustainable costs would directly benefit AI model training, inference at scale, and edge deployment. The current bottleneck for many AI applications is compute availability and cost.

Gelsinger frames semiconductor advances and AI progress as inseparable. Breakthroughs in chip lithography enable breakthroughs in AI capability. The trillion-dollar market pulled forward to 2026 reflects that symbiosis.

Frequently Asked Questions

What is xLight and what does it do?

xLight is a semiconductor startup developing novel lithography techniques to manufacture chips using light wavelengths smaller than the current 13.5-nanometer standard. It's backed by Playground Capital and the US government.

Why did Pat Gelsinger leave Intel?

Gelsinger departed Intel as CEO in late 2024. He has not publicly detailed the specific reasons but spent the following months evaluating his next role before joining Playground Capital in March 2025.

What is Moore's law and is it still valid?

Moore's law predicted that transistor density on chips would double roughly every two years. While the trend held for decades, physical limits on shrinking transistors have slowed progress. Gelsinger believes new lithography techniques could restart the trend.

When will the semiconductor industry hit $1 trillion?

According to Gelsinger, the industry now expects to reach $1 trillion in annual revenue in 2026, accelerated from the previous 2030 target due to AI-driven demand.

What is Playground Capital?

Playground Capital is a venture capital firm specializing in deep tech investments, backing startups built on new science rather than software. Gelsinger joined as general partner in March 2025.
